PAESTEURIEING APPARATUS.

Application filed l,

This invention relates to apparatus for Pasteurizing; milk or for similar purposes and has for its principal objects the simplitication of such apparatus and a more ellecii e and quicker application of heat-or cold to the liquid being treated, together with features which make it easier to keep the apparatuscin sanitary condition.

In the drawings hereto:

Figure 1 is a vertical section of a conventional milk container with a hollow paddle therein supported for oscillation and arranged for circulation within the paddle of heating or cooling; liquids or gases, and

Figure 2 is a cross section of the paddle only taken along the line 22 of Figure 1.

l Jith reference to the drawings, 1 is a milk container with a rounded bottom having; an outlet at 2 and an angle or flange at 3.

l l ithin the container is suspended any number of paddles each of hollow oval section l with rounding lower ends 5 and rounded upper corners 6.

The paddle is spaced from the sides and bottom of the container as shown and provided inside with partitions 7, a central parlit an 8 and suspended on a pipe 9 communieating with its interior with certain relation to the partitions and rotatably supported in the bearing 10 mounted. on the an ole 3 so that upon oscillatingthe pipe within the bearing' the paddle will be swung back and forth in any milk placed in the containlVithin the pipe 9 is another pipe 11 arranged to open adjacent the central partition 8 so that whatever liquid or gas is sent through it into the paddle will be deflected and follow the direction of the arrows back and "forth until it finds outlet in the larger pipe 9.

Any suitable means is provided for operating the paddle permitting a number of them to be hooked up at once, and in the drawing such means is indicated'by a crank arm 12 having a connecting; rod 13 extending to one crank 19 of a crank shaft 20 so that upon slow revolution of the shaft the paddle will swing gently back and'forth in the milk, while the Pasteurizing; heatis communicated to the milk by forcing a properly heated Serial No. 27,915.

fluid through the paddle as described after which by suitable valve arrangement not shown the hot fluid is exchanged for a coolll one to effect the desired rapid cooling oi the milk. v

To permit oscillating motion of the pipes the ones pass into a fined chamber or T 14;,

the outer pipe 9 being loosely threaded at 15 to the chamber and prevented from leaking by gland stutfing box 18 of conventional co. uction, while the smaller p pe 11 entends further into the enlarged interior of the chamber where it is loosely screwed into s l r elbow 16 havlno' a n1 e17 firml 1 J 1 c: i I v9' at ris'ut an les therefrom and i1: 1 o b n s dlSO screwed tightly through the side of the "l" 14:.

Thus when the )addle 1S oscillated as de- G l '1 scribed the threaded ends of pipes 9 and 11 will screw slightly back and forth in the.

large T but will be effectually prevented from coming ofi while the st-utling boX' I5 steps all leakage from the chamber.

Any slight leakage from the inner screw joint of the smaller pipe within the chairber is of no consequence as it simply flows to the outlet 18, tho it is evident to any mechanio that the inner pipe joint could be packed also it desired.

he paddle is preferably made entirely of brass or non-corrosive metal and, owing to its smooth external shape, is easily kept ing with the interior thereof, said pipes being arranged one within the other, a bearing; supporting the outer pipe for oscillatory 1notion of the paddle a crank secured to the outer pipe, means for oscillating the crank, a plurality of vertical partitions depending from the inner said pipe and a plural ty of partitions disposed alternately to the first mentioned partitions anch rising from the bottom of the said peddle.

2. In a Pasteurizinp; apparatus container, a hollow movable paddle Within the cont iiner, a pipe communicating with the interior of said paddle, said peddle being adapted to hold a liquid, a second pipe C0111- ninnicnting with the interior of said paddle a pluulity of vertical partitions depending from said second pipe and a plurality of partitions disposed alternately to the first mentioned partitions and rising from the bottom of said paddle.
